To all whom it may concern: 1

Be it known that l, CHAnLns S. CASE, a citizen of the United States,residing at Lestershire, in the county of Brooms and State of New York,have invented certain Improvements in Bloclrdianclling Devices, of whichthe following description, in connection with the accompanying drawing,is a specification.

This invention relates to machines for cutting sheet material, such asleather for use in the manufacture of boots and shoes, and moreparticularly to machines for woking upon heavy material, such as soleleather, in which it is necessary to employ a cutting block or bed ofconsiderable size and weight. In'machines of this character the workingface of the block becomes scarred and worn by the action of the die, sothat it is necessary frequently to change'the position of the block inorder to obtain a smooth and even cutting surface, or to remove theblock entirely from the machine for the purpose of planing its workingface or in order to substitute another block. At the same. time it isimportant that the block, when in working position, should rest upon arigid support, such as a stationary part of the framework of themachine, and be secured against lateral movement,'in order. to opposeunyielding resistance during the cutting 0peration. In previous machinesof this character it has been necessary for the operator,

- di'lliculty.

in moving the bloclcto grasp it and lift it bodily from the support, anoperation attended with considerable inconvenience and The object of thepresent invention is to provide in a machine of the character specified,means for facilitating the turning or removal of the block.

The invention is illustrated as embodied in a sole cutting machine butit will be understood that it is applicable broadly to all machines ofsimilar character in which it is necessary at times, to remove or changethe position of the cutting block.

In the drawing, which represents in elevation a sole cutting machinehaving certain portions broken away to show more clearly my improvementapplied thereto, 1 indicates the cutting block and 2 the beam thatreciprocates above the block and on its descent engages the die or diesto effect thecutting operation in the manner characteristic of this typeof machine. The block 1 rests upon the fixed support 3 which is formedin the present instance with a flat bed plate 4 for supporting equallyall portions of the block.

For the purpose of raising the block and changing its position, I haveprovided the turn table 5 which is located beneath the block and in theform of the invention shown is countersunk in the face of the bed plate4, with its upper face normall in the same plane as the face of the bedplate, in order that all portions of the block may be supported equallywhen in working posi tion. The turn table is provided preferably withprojections 6 for engaging the lower face of the block to prevent theblock from turning with respect to the turn table when supported thereonand is swiveled upon the end of a screw 7 that turns in the support 3and is provided with a hand wheel. 8. When it is desired to change theposition of the block the operator turns the screw 7, thereby raisingthe turn table sufficiently to clear the block from the supportingmeans. Since the turn table turns freely upon the end of the screw, theblock may then be swung easily to any position and lowered again. uponthe bed plate. For the purpose of facilitating the removal of the blockfrom the machine I have provided the roller 9 which is locatedpreferably on the front of the bed plate and projects slightly above itsface. lVhen it is desired to remove the block, the latter is first swungto the dotted line position by the means previously described. Bytilting the front end of the block downwardly upon the roller, and usingthe roller as a fulcrum the block may then be freed from contact withthe turn table, and by aid of the roller readily re and without thenecessity for lifting the blockentirely clear of the machine during theprocess of removal, By a reversal of these operations, the block may bereturned moved from the machine without friction Patent of the UnitedStates is the followmg:

1. In a machine of the character described, the combination with a blockand a support arranged to be engaged by the lower surface of the blockwhen the block is in working position, of means for raising the blockfrom engagement with the support, said means being constructed to permitthe block when thus raised to be turned readily to different positionswith respect to said support.

2. In a machine of the character described, the combination with ablockand a support constructed and arranged for engagement with theblock, of a turn table located beneath the block and vertically movableto raise the block from contact with the support.

3. In a machine of the character described, the combination with acutting block and a support arranged to be engaged by the lowersurface'of the block, of a turn table located beneath the block andvertically movable to raise the block from contact with the support,said turn table having projections for engaging the lower surface of theblock to increase frictional resistance to relative turning movement ofthe block and turn table.

4C. In a machine of the character described, the combination with acutting block and a support arranged to be engaged by the lower surfaceof the block when the block is in working position, of a turntablelocated beneath the block and vertically movable to raise the blockfrom the support, and means for raising the turn table.

7 5; In a machine of the character described, the combination with acutting block and a support therefor, of a turn table located beneaththe block with its upper surface substantially in the plane of thesupport when the block is inworking position, said turn table beingvertically movableto raise the block from the support, and a screw forraising the turn table.

6. In a machine of the character described, the combination with acutting block, of a bed plate for supporting the block, and a verticallymovable turn table countersunk in the bed plate, the upper face of theturn table being normally in the same plane as the face of the bedplate, whereby all portions of the block when in Working position may beequally supported.

7. In a machine of the character described, the combination with acutting block, of a bed plate for supporting the block, a turn tablecountersunk in the bed plate, and means for raising the turn table tolift the block from the bed plate.

8. In a machine of the character described, the combination with acutting block, of a bed plate for supporting the block, a turn tablecountersunk in the bed plate, and a screw for raising the turn tablefrom the bed plate, the turn table being swiveled upon the end of thescrew.

9. In a machine of the character described, the combination with acutting block and a support for the block, of means for raising theblock and permitting it to swing to different positions with respect tothe support, and an anti-friction device on the front of the supportcooperating with the turn table to facilitate the removal of the blockfrom the machine.

10. In a machine of the character described, the combination with acutting block and a support for the block, of a vertically movable turntable for raising the block and permitting it to swing to differentpositions with respect to the support, and a roller on the front of thesupport cooperating with the turn table to facilitate the removal of theblock from the machine.

11. In a machine of the character described, the combination with acutting block and a bed plate for supporting the block, of a turn tablelocated in the bed plate means for raising the turn table to lift theblock from the bed plate, and a roller on the machine in front of thebed plate cooperating with the turn table to facilitate the removal ofthe block from the machine.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
